In software engineering, gold is a linker for ELF files. It became an official GNU package and was added to binutils in March 2008  and first released in binutils version 2.19. gold was developed by Ian Lance Taylor and a small team at Google. The motivation for writing gold was to make a linker that is faster than the GNU linker, especially for large applications coded in C++.
Unlike the GNU linker, gold doesn't use the BFD library to process object files. While this limits the object file formats it can process to ELF only, it is also claimed to result in a cleaner and faster implementation without an additional abstraction layer. The author cited complete removal of BFD as a reason to create a new linker from scratch rather than incrementally improve the GNU linker. This rewrite also fixes some bugs in old ld that break ELF files in various minor ways.

eu-elflint has a flag '--gnu-ld' described as "Binary has been created with GNU ld and is therefore known to be broken in certain ways". Note that by GNU ld the original GNU binutils ld is meant, not the newer GNU binutils gold linker.
